Unfortuantly I left a lens on the table with the little ones around and typically it ended up on the floor. Its a Canon 18-135 STM, No visible marks on the outside but lens will not zoom all the way out, exif data shows 100mm to be the max, when zooming in or out you can feel like a click around the 30mm mark. It also does not focus correctly, at its widest (3.5-5.6) the photo is very out of focus but stop it down to 11+ its in focus.

Can't imagine id get much for a damaged lens on eBay so rather see if it can be fixed diy. Anyone with any advice on what the actual damage is or taking the lens apart etc is appricated.
 
Besides the obvious opportunity to upgrade :) have you got accidental home insurance? I'm not familiar with Canon equipment but after an initial look over to see if there is anything you can do, places like Fixation or maybe even Canon service aren't a expensive as you might imagine, or a direct secondhand replacement. At work we had a couple of Nikon lenses that wouldn't focus. A quick look revealed the lens body slightly askew. When all else was lost, a couple of thumps and surprisingly everything popped back into place. They had suffered knocks in the first instance and another knock sorted it out. They worked perfectly after. they were cheaper consumer grade (16-85 VR)

Unfortuantly no excuse for that as this was just a spare lens that came with a camera I bought, not the kinda lens I use for photography but kept hold of it as its an STM lens so would of been handy for videos.
No claimings not an option either I'm afraid. Although I'm not too worried about the money as its a very low value lens which is why I wouldnt want to spend money sending it for repair either.
Just seems a shame to throw it away and only going to get peanuts selling a damaged lens so thought good as excuse as any to get the tools out.
Surprising the simple solutions that can work, looking at it I can't see anything a miss though, nothing broken and all seems to line up, must of jolted something out of place inside the lens.
 
Well stripped it down and found a broken tab and screw that was blocking it from opening up to 135mm. The zoom part works now but the manual focus doesn't work and the auto focus doesn't seem to be too good below 50mm yet above that it's spot on.

Sounds like it's time for an upgrade / replacement then - personally, I would have thought it was getting close to the cost of not worth the cost of repairing it (if that makes sense), but could be worth a couple of phone calls to get an idea on repair cost...

Well thankfully its not a lens I normally used for photos, just kept it for video because of it being an STM lens. Definitely not worth sending off to repair for me, be going on ebay as faulty and hopefully someone who's a little more knowledgeable will be able to fix it as a shame to chuck it with such little use.
